A Application led February 2S, 1917. Serial No. 151,435.

To all whom t may concern:

Be it known that l, ELIJAH R. HILL, a citizen of the United States, and resident of New Albany, in the county of Union and State of Mississippi, have invented a new and lmproved Flush-Tank Valve, of which the following is a full, clear, and exact de-k scription.

This invention relates to baths and closets v and has particular reference to flush tank apparatus.

` With the foregoing and other objects inv view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the inventionis not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a vertical sectional view of my improved device shown as applied to a flush Fig. 2 is a transverse sectional detail on the line 2-2 Fig. l.

Referring now more particularly to the drawings l show one preferred embodiment of the invention, subiect to Such variations or modilications as 'fairly fall within the scope oie this specilication. As shown, my improvement comprises a bracket l including a base 'll irom which proyects down wardly a Spud 12 through the bottom oi the tank 13, the bracket and spud being locked rigidly and tightly in position in any usual manner as by means of a nut lli threaded upon the Spud, and the lupper end of an inlet or supply pipe 15 is connected to the spud as by means of a coupling 16. rl`he bracket also includes a pair oi' upwardly projecting standards 17 and 18 arranged preferably on opposite sides of the base 1l. lhe base is provided with a central threaded socket i9 at the lower endof which is formed a shoul der 20.

rlhe valve mechanism includes a nozzle 21 having a threaded boss 22 tted into the socket 19. and provided preferably with a base ange 23 abutting against the upper surface ofthe base 1l. Said nozzle is formed with a central' bore 21 formed in alinement with the-anis or" the spud bore l2. The upper end of'thenozzle constitutes the valve sea-t and theouter surface ofthe nozzle is so constructed as to consist of two diiierent sizes of cylindrical portions, the larger of which is indicated at 24, while the smaller is indicated at 25.

The movable portion of the valve comprises a sleeve 26 of tubular construction but having larger and smaller cylindrical portions 26a and 26b cooperating respectively with the larger and smaller portions of the nozzle. rlhe two diil'ercnt sized portions of the sleeve are spaced equally from the respective portions of the nozzle which they surround, providing a passageway 27 through which the water is adapted to flow from the supply pipe into the tank. rlhe outlet thus provided for the water from the valve being directed downwardly toward the bottom of the tank practically and in a simple manner eliminates all splashing and noise commonly incident to the rush of the water. llhe upper end of the sleeve portion 2Gb is externally threaded to receive a cap 28 between which cap and the upper end of tank. and a f 'the sleeve is fitted any suitable type of gasket or washer 29. The periphery of the washer being gripped between the cap and the end of the sleeve is held in fixed position 'with respect to the other parts of the valve and in position to seat squarely upon the aforesaid valve seat. Between the sleeve and the nozzle extend a'plurality of lugs 3() which span the space 27 and serve to hold the sleeve properly spaced `from and concentric with the nozzle. These lugs 30 may be carried by either of these parts and project toward and into contact with the other. As indicated they are made as integral parts of the sleeve.

' At 3l. l indicate a yoke shown as in the nature of an open loop, the two free ends ci" which are applied to opposite sides oi' the upper end of the standard i7 and through which is passed a pivot pin 32. vThat portion or the yolre diametrically opposite the .llltll pivot consists of a lug 33 to which is pivoted a link 34 by means of a pivot pin or bolt 35. The two side portions of. the yoke extend on opposite sides of the sleeve 26 and preferably spaced slightly therefrom to insure freedom of movement. I provide, however, pin and slot connections between the yoke and the sleeve whereby movement of the yoke in either direction will cause endwise movement of the sleeve. According to the illustration the pins or lugs 36 are formed as integral parts of the sleeve and project radially outwardly therefrom into the slots 37 formed in the side portions of the yoke, with the longer dimensions of the slots transverse to the direction of movement of the sleeve.

A bell crank 38 is pivoted at 39 upon the upper end of the standard 18, the shorter armoil thebell crank extending horizontally toward the valve mechanism and being pivotally connected at 40 with the upper end of' the link 34. The ball iioat 41 is rigidly but adjustably connected by any suitable means well known in the art to the upper end of the bell crank. V

, When the water is withdrawn from the tank by any suitable means with which this particular invention is not directly concerned, the iioatball 11 drops with the water as usual swinging the bell crank around its pivot 39 andthe weight of the ball serves to lift the yoke- 31 swinging it upwardly around its pivot 32, as indicated in dotted lines in Fig. 1. This upward movement of the yoke causes through the lug and slot connections 37 the upwardly unseating movemento the valve sleeve 26 allowing the water to iiow upwardly through the nozzle whence it is deiected downwardly through the space 2l' refilling the tank and causing the lifting of the ball float whereby when the level of the water reaches the predetermined plane the positive seating of the Avalve washer 29 is edected. if desired any suitable torni or construction of strainer 42 may be interposed in the inlet mechanism as ttor example in the upper end of the spud where the periphery oithe strainer is gripped between neaeei the lower end of the boss 22 and the shoulder 20. A. strainer of this character serves to prevent any solid particles such as sand, scale, grit or the like from destroying prematurely the washer 29. also indicate at 43 a suitable refilling tube carried by the sleeve and communicating with the space 27- automatically control the position of the valve, said valve also including a cap carrying a gasket and removable from the upper end of the sleeve without disturbing any other part of the device. l'

2. In a flush tank valve, the combination olZ a rigid base having a central threaded socket and a pair of upwardly projecting standards on opposite sides thereof, a nozzle having a boss removably fitted into said socketand supported thereby rigidly upon the base, the opposite end of the nozzle constituting a valve seat, a strainer held in the socket between the base and the nozzle, a sleeve iitted in spaced relation over said nozzle and having an open end adjacent to the base, the opposite end ot the sleeve being sealed and 'coperating directly with said spo seat, and an elliptical yoke pivoted at one y El fil? klit"
